Cate Blanchett is "completely in love" with co-star Harrison Ford.
The 38-year-old actress - who stars alongside Harrison in '"Indiana Jones and the Kingdom of the Crystal Skull" - always admired Harrison's portrayal of the adventurous archaeologist, but has developed a full-blown crush on him since they started working together.
She told Empire magazine, "I was such a fan of the 'Indiana Jones' movies, I grew up on them. I was completely in love with Harrison Ford, and I still am! He's a hottie, and has definitely stood the test of time."
"It's so much fun doing this film, I've been having a ball. It's like a family, everyone is so welcoming. It is a really happy set to be on."
Last week, a film extra revealed Cate will play an evil interrogator who tortures Jones in a bid to discover the whereabouts of a priceless skull.
Meanwhile, movie bosses are said to be determined to ensure Harrison looks his best in the latest installment of the adventure series.
The 65-year-old actor has reportedly been given a $10,000-a-week hair and make-up budget. Producers are also said to be paying $4,000-a-week for a personal trainer to whip the star into shape.
A source said, "Harrison is in great shape but he is getting a lot of help behind the scenes. He has no problem acting the part, but bosses were keen to make sure he looked as good as he did 26 years ago in 'Indiana Jones and the Raiders of the Lost Ark'."
"Indiana Jones and the Kingdom of the Crystal Skull" is released worldwide on May 22 next year.
